'The holy Apostles remained in seclusion and applied themselves to prayer from the Ascension of Jesus Christ until the day of Pentecost. This was a feast that the Jews celebrated in memory of the giving of the Old Law to Moses on Mount Sinai. On this day the Holy Spirit descended on the Apostles and on all those who were gathered together with them in the large upper room. He came to bring them a new law, the law of grace and love, and he poured himself out upon them like a strong, driving wind.

This was to show that just as God in creating man had, as Holy Scripture expresses it, breathed into him the breath of life, so too in communicating a new life to his disciples to live only by grace, he breathed into them his divine Spirit to give them some share in his own divine life.'

St. Jean Baptiste de la Salle
